The Lowdown
Righto, let’s have a look at what’s comin’ our way for Jaconé, just down the coast. It’s a bit of a slow starter, but once it gets goin’, there’s some proper grunt in the tank for the experienced crew.
The water’s sittin’ at a nice 73°, which is a touch warmer than normal for this time of year – that’s a little bonus.
First up, Friday the 7th and Saturday the 8th are pretty much write-offs. Tiny swell, light onshore or cross-off breezes, and the energy’s weak (77 and 53). You’d be fightin’ for a dribble, not worth paddlin’ out.
Then Sunday the 9th mornin’ – that’s where it wakes up. Clean, cross-off wind from the north, light breeze, and a solid 7ft SSW groundswell (14-second period) rollin’ in. The combined energy jumps to 1573, so there’s serious push. This is expert territory – too big for beginners. The long period means it’ll have some lulls between sets, but the shape will be there. The afternoon gets blown out by an onshore westerly, so get in early.
Monday the 10th and Tuesday the 11th keep the size up around 7ft to 8ft, still S-SSW swell. Tuesday is the standout of the first week: both mornin’ and afternoon have clean, cross-off winds, solid energy (2137 and 1937), and excellent conditions for experienced surfers. The period’s around 12-13 seconds, so good lines, but still a big, powerful wave.
Wednesday the 12th through Friday the 14th remain in the 6ft to 8ft range, with early offshores or clean cross-off winds on the mornings. The swell is consistent, and the energy stays high (well over 1000). The wind does pick up on the afternoons, so the dawn patrol is your friend. Friday the 14th has a very long period of 15 seconds from the SSW, but it’s onshore, so the swell’s gonna be a bit of a washout with that wind.
Come Saturday the 15th and Sunday the 16th, the swell’s droppin’ back to 4ft to 5ft, and the wind’s a bit mixed. Not the best windows.
Then there’s a gap until Tuesday the 19th – nothing really worth jumpin’ out of bed for those days.
Wednesday the 20th afternoon sees a fresh pulse: 7ft SSW swell, clean cross-off wind, and combined energy of 779. That’s a solid, good-quality session.
Now, the big one – Friday the 21st morning. The forecast is showin’ a 10ft SSW swell with a 12-second period, and the energy is massive at 2734. The wind is light and cross-off from the ENE. This is a serious, expert-only wave. It’s predicted to be too big for the break, so only the most experienced should even think about it. The afternoon drops to 8ft, still plenty of juice.
Saturday the 22nd wraps it up with a still-strong 7ft S swell, clean and light winds, and excellent conditions for the experienced crew. The energy’s sittin’ at 1037.
The standout sessions:
If you’re experienced, you cannot miss Tuesday the 11th – both sessions are clean, powerful, and consistent with that 8ft S swell. The other big one is Friday the 21st morning, but only if you’re a proper charger – that 10ft is a beast.
Keep an eye on the wind, because the mornings are the ticket. The rip might be runnin’ with that size, but it’ll make paddlin’ out easier.

Information about the Jaconé Surf forecast
The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Jacone is 14 km (9 miles) from the city of Saquarema. If you plan a holiday in Rio de Janeiro, look for hotels and other accommodation in Saquarema. Saquarema has rooms for a wide range of budgets as well as car hire and transport links.
